Connection arrangement for a tube like fuel line
Abstract:
There is described a connecting arrangement for a fuel line (5) which extends through a passage (4) of a cylinder head (1) to a nozzle holder (2) to feed fuel to an injection nozzle. The fuel line has a pressure nipple (6) which on its front side has a sealing surface (8) and on its rear side a pressure receiving surface. A cap screw element (15) which surrounds the fuel line and is screwed to the inlet opening (3) of the passage projects into the passage with an axially directed tube portion (17) which in the tightened condition exerts on a pressure transmission arrangement a force which is directed axially towards the nozzle holder and which is transmitted to the pressure receiving surface of the pressure nipple to press its sealing surface against a counterpart sealing surface (10) on the nozzle holder. A sealing arrangement which seals off a first free space (21) between the outside wall of the fuel line and the inside wall of the pressure transmission arrangement and a second free space (22) between the outside wall of the pressure transmission arrangement and the inside wall of the passage relative to the exterior is positioned completely in the interior of the passage.
